Document Summary
Review sessions thursday 7:15pm @ food science aud, saturday 1pm enr building. We focus on the effects on carbon. There has been a huge fluctuation over time. Related to temperature, if temperature goes up, carbon increases. If there is a lot of input temperature is higher, if there is low inputs temperature is low: as heat comes off of the earth, co2 traps the heat. If venus did not have co2, its temperature would be below 0. Co2 has been increases over time, especially over the last 150 years when industrial revolution started. The rate of the fluxes are increasing, each gas holds temperature differently: cfc"s hold the most heat. Residence time: cannot fix the problem over time. Nitrogen triflouride (nf3) very potential, 1700 x the heating potential of co2 we have been producing this over the last couple of years because it is in the process of making flat screen tvs.
